Trimble introduces lassen DR+GPS Module for Vehicle and Asset Tracking applications

SHARE

Hannover, Germany, 15 March 2007: Trimble introduced today the Lassen® DR+GPS module that combines dead reckoning (DR) with Global Positioning System (GPS) technology on a single, compact board. When GPS signals are limited or not available, such as in urban canyons and tunnels, the Trimble Lassen DR+GPS module provides reliable and accurate positioning information. It is an ideal solution for system integrators or OEMs who are adding location capabilities to vehicle navigation, fleet management and asset tracking systems.

The Lassen DR+GPS module accepts inputs from an analog gyro, an odometer pulse and a forward/reverse indicator. Its sophisticated DR+GPS algorithm automatically calibrates these sensors and optimally blends the sensor inputs and GPS to produce accurate position and velocity outputs in hostile GPS environments such as urban canyons.

“Trimble has been a leading supplier of dead reckoning technology for vehicle applications for nearly 15 years and has shipped over one million DR+GPS custom units,” said Steve Ruff, general manager of Trimble’s Embedded Technologies. “In the past, dead reckoning integration was considered too complex or expensive for most commercial applications. Today, the Lassen DR+GPS module makes dead reckoning integration easy and cost-effective with features such as automatic sensor detection and calibration. Trimble has simplified the complexities of DR and has made its integration more practical for a broad range of vehicle and asset management applications.”
